Application filed october 5, 192s. serial No. 310,627.

This invention relates to new and useful improvements in' registers for hot air heating systems. Y

The prima-ry objects of the invention are 5 the' proyision of a hot air register which is of simple but durable `construction and is so constructed` that al'lcre-vices and regular surfaces, which may provide lodgment for dirt and dust and are inexcessible for cleaning 1U purposes, are eliminated, thereby providing a register whichis'ea'sy to clean and is sanitar Y ther objects of theV invention are to provide af hot air register which contains but few 15 parts and can beeconomically manufactured and whichV can be readily attached to and detached from the hot air register frame and which hassimpjle means for locking: the closure member either in` open or closed posi- With these and-othery objects in view, our invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed,

Referring'byr numerals to the accompanying drawings-10 indicates-a register frame" which is placed against the wall and vforms the discharge opening for the hot air duct. This frame consists of an inwardly presented marginal flange 11 which forms the terminus for the hot air duct and a vertically disposed iiange 12 which is arranged against the wall. A register or grille member 13 is detachably secured within the opening formed by-iiange 11.

This register consists of a pair of horizontally and longitudinally disposed members or rods 14 and 15, forming, respectively, top and bottom members of the grille and adapted to be placed against the horizontally disposed Harige members 11n and 11b, respectively. Longitudinal members 14 and 15 are united by a series of transversely disposed members consistingof end members 16 and intermediate members 17. Members 14, 15, 16, and 17 are preferably formed fromr rods of suitable diameter cut to the desired lengths.

Members 16 and 17 are secured at their ends to longitudinal members 14 and 15, preferably by welding. This not only results in a simple and durable construction but also provides smooth surfaces which can be readily cleaned and do not contain any pockets 0r recesses for catching dust.

The ends 14L of top member 14 are slightly offset 4downwardly and receive tubular eXtensions or hinges 18 of members 19, which latu ter are secured to a closure plate 20. Thus said plate ishingedly mounted on said grille and can be operated to open and close or control the communicationor passage of hot air through said grille. .This closure is disposed vrearwardly of the grille and opens rearwardly or inwardly thereof as shown in Figure 3. A handle 21 is fixed to said plate, preferably intermediate the ends thereof and near the upper end of same. This handle projects forwardly between the central pair 17a Iof intermediate rods 17;

The bottom flange 11b has pressed outwardly and upwardly therefrom a seriesofI lugs or`pr`ojections 22, preferably arranged in pairs near each end thereof. These ears o r lugs are spaced from each other the thickness of thebottom rod 15 and when grille 13r is inserted inY the frame 11, said bottom member is received between said lugs and is held thereby in position 1n Vthe frame.

The vertically disposed flange membersV 11c are provided, preferably near the upper ends thereof, with a. pair of lugs or ears 24 which project laterally therefrom and form stops for the vertically disposed end-members 16.. A shoulder 25 is pressed inwardly and laterally from each liange member 11c near lug 24 and is spaced forwardly `therefrom so as to receive between said lug 24 and said shoulder 25 the vertical rod 16. Each shoulder 25 projects outwardly from Aflange 11a onlf,T a short distanceso that vVertical rods 16 can be snapped in position past said shoulders. The forward face of each shoulder25 is formed inclined or tapered as indicated at 25a to facilitate the positioning of thegrille. small diameter and are of suitable lengths, they possess afcertain degree otresiliency and can be readily snapped in position or detached from the frame by applying pressure to said members.

The handle 21 is adapted to be locked so as to hold the closure `plate 2() in any adjusted position. This locking means consists of an eccentrically mounted disk 26, the edge of which is adapted to bear against the inner face of a curved portion 21a. This curved portion is preferably concentric with the hinges 18 and the inner face is roughened or serrated as indicated at 21b in order to provide a better hold for disk 26. The latter is eccentrically mountedby means of a pin 27 on the transverse portion 28 of a bracket 29. The ends of the bracket are secured to the intermediate bars or rods 17*il as indicated at 30. The intermediateportion 28 is provided with an elongated horizontally disposed slot 31 through which the curved portion 21 operates. Disk 26 is formed with an upwardly projecting handle 26L by means of which said disk may be actuated. When said handle occupies upward central position shown in Figure 9, vdislr 26 is disengaged from curved portion 21a and handle 21 and.

closure plate 20 are free and occupy closed position as indicated in Figure 2.

To lock the plate in open or adjusted position, handle 26 is operated to either side of its central position, thereby` bringing the eccentricallydisposed portions of disk 26 into engagement with the roughened surfaces 21b so as to lock said handle against movement. VThis construction provides a simple and inexpensive lock which is easy to operate and will securely hold the plate in locked position. y

In inserting the grille 13 in position in frame 10, closure plate 2O is so placed asto position the lower edge thereof behind lthe rear lugs 22, while 4the bottom rod 15 is placed between the front and rear` lugs 22, This precaution is necessary as otherwise it As rods 16 are of comparatively stances..

Qur improved register is of simple and inexpensive construct-ion, and is sanitary, being easily cleaned and being devoid of all pockets or crevices in which dust and might find lodgment.

It is obvious that our improved, register is susceptible of various structural changes and. such v modifications'` and we contemplate changes and modifications as being; within the spiritof our invention. i
